Answer: Is 72 21/64
Multiply 12 times 6 that's 72. Then multiply 3 times 7 and 21. And then multiply 8 times 8 and get 64.
The correct answer for the question that is being presented above is this one: "<span> C. The mean is decreased by about 1.2 and the median is decreased by 2." </span>For the data shown in the stem-and-leaf plot, the effect on the mean and median of adding the value 10 to the data set is that t<span>he mean is decreased by about 1.2 and the median is decreased by 2.</span>

Answer:
The length of x is 4
Step-by-step explanation:
The scale factor is Large/small where 10/8 which is DF/AC.
THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.
5/4 = EF/BC
5/4 = Y/6
Y= 7.5
info: use CORRESPONDING ABC AND DEF .
Use substitution and substitute y into the other equation. One of the equations already gives you y in terms of x, so use that and substitute it into the other equation. y = 3x - 4
Plug into the other equation: -3y = -9x + 12
-3(3x-4) = -9x + 12
-9x + 12 = -9x + 12
This is an identity. So that means that any value of x makes this equation true. So B.
